刺角天牛(Trirachys orientalisHope)据文献记载分布河北、北京、山东、河南、江苏、上海、浙江、福建、四川、海南及台湾等省(市)。据在济南调查危害柳树、合欢、国槐、刺槐、毛白杨、银白杨(见于北京)、银杏等树木的枝干,以20年生以上的大树和老树受害较重;柳树是济南的市树,受害最重。但迄今为止,对刺角天牛生物学特性研究报道甚少。为此,我们自1986年对其生物特性进行了较系统的研究。本文仅将刺角天牛幼虫龄期测定和幼龄阶段积温两个方面报道如下。

Trirachys orientalis Hope is located in the provinces (cities) of Hebei, Beijing, Shandong, Henan, Jiangsu, Shanghai, Zhejiang, Fujian, Sichuan, Hainan and Taiwan. According to a survey in Jinan, trees and old trees harming willow, acacia, Sophora japonica, black locust, white poplar, silver poplar (found in Beijing) and ginkgo trees are heavier than trees and old trees over 20 years old; Tree, most affected. So far, however, little has been reported on the biological characteristics of Horned Beetle. To this end, we have conducted a systematic study of its biological characteristics since 1986. In this paper, only the sedge horn larvae age determination and young age two aspects of temperature are reported below.
